ITMO Researchers Develop Unique Printing Technology for ‘Invisible’ Images

Researchers from ITMO University’s ChemBio Cluster have developed an inkjet printing technology that makes it possible to produce images that can only be seen in polarized light – such as when using a smartphone screen. The new technology will help manufacturers protect their products from forgery. An article concerning the technology was published in ACS Applied Material Interfaces.

In order to achieve these results, the researchers have spent 5 years working on a way to use solution chemistry methods to apply high-resolution organized nanostructures. In large part, the ability to produce images invisible to the naked eye is thanks to the creation of special
